BOARDMAN E. TREIBER, OF SYRACUSE. NEW YORK.

PAPER-FASTENER.

Application filed March 28, 1919.

T 0 all whom it may concern:

Be it known that I, BOARDMAN E. Tim-Inna, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and 4 State of New York, have invented a certain new and useful Paper-Fastener, of which the following is a specification.

This invention relates to paper fasteners and has for its object a particularly simple, efficient and economically manufactured paper fastener which is readily detachable from the paper when desired.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designatecorresponding parts in all the views.

Figures 1, 2 and 3 are respectively a plan, inverted plan, and longitudinal sectional view of a paper fastener embodying my invention.

Fig. d is a plan view of the blank from which the paper fastener shown in Figs. 1, 2 and 3 is formed.

Fig. 5 is a view of a modification of the blank shown in Fig. 4.

Fig. 6 is a sectional view of a modified form of the fastener.

Fig. 7 is a plan view thereof.

Fig. 8 is a plan view of the blank from which the fastener shown in Figs. 6 and 7 is formed.

This paper fastener comprises generally, opposing jaws, a bend connecting the jaws and pinch handles extending from the jaws and beyond said bend, the jaws having respectively a coacting prong and perforation.

1 and 2 are respectively the jaws and 3 the bent portions connecting the jaws.

4L and 5 are the pinch handles connected to the aws 1 and 2, the pinch handle 1 being struck from the portion of the blank forming the bends 3.

The pinch handle 5 is part of a flap 6 bent upon the outer face of the jaw 2 and extending beyond the bends 3. The jaws 1 and 2 are provided respectively with a coacting prong 7 and a perforation 8 near their free ends, and the flap 6 is also formed with a boss or cap 9 covering the perforation 8. Preferably, as seen in Fig. 3, the margin of the wall around the perforation 3 is turned downwardly to form a ring or tubular lining for the perforation.

Specification of Letters Patent.

Serial No. 285,712. Y

The fastener shown in Figs. 1, 2 and 3 is formed from an oblong blank 10, Fig. 4:, including a main body 11, and a flap 12 at one end of the main body. The'main body is formed with the perforation and prong 8 and 7 at its opposite ends, and is formed between its ends with a U-shaped cut 13, the arms of which are parallel to the side edges of the body 11, this cut forming a tongue which when the body 11 is bent upon itself, forms the tongue or handle 4 joined to or integral with the jaw 1 and located between the bends 3.

The flap 12 is also formed with the boss or cap 9 and is bent backwardly and outwardly upon the contiguous half of the body forming the aw 2 and the extreme outer end portion of said flap extends beyond the bends 3 to form the handle 5. The cap 9 covers the perforation 8. However, as seen in Fig. 5 the flap designated 15, instead of being in line with the body may be joined thereto at one side and folded laterally along lines 16 upon the top or outer face of the half of the blank forming the jaw 2, or as seen in Fig. 8, two flaps 17 may be arranged on opposite sides of the portion of the blank forming the jaw 2 and folded laterally over onto the top of the jaw 2 and the rear end portions extended beyond the bends 3, to form the handle.

In this construction, the part of the blank forming the jaw 2 is not formed with a perforation but is provided with a boss or cap 18, and an annular die or rib 19 projected into the space between the jaws.

In operation, the sheets of paper are placed between the jaws and the jaws pressed toward each other to'cause the prong to pierce the paper in the usual manner. To detach the fastener the handles 4, 5 are pinched toward each other to separate the aws.

This fastener construction is particularly advantageous in that it provides a particularly simple and economical way of applying handles to the jaws.

lVhat I claim is:

1. A paper fastener comprising a single strip of flexible metal bent to form opposing jaws, the jaws being formed with a complemental prong and opening, and one of the jaws having a lengthwisely extending tongue projecting beyond the bend connecting the jaws, a flap associated with the other jaw and folded upon the same and having a ioo portion thereof ertending beyond the bend connecting the jaws into a position opposed to the rearwardly projecting portion of the former jaw, said tongue and projecting portion forming pinch handles, substantially as and for the purpose described.

2. A paper fastener comprising a single strip of flexible metal bent to form opposing jaws, one of the aws having a lengthwisely extending tongue extending beyond the bend connecting the jaws, a flap extending lengthwise of the other jaw and folded tending beyond the bend connecting the jaws into a position opposed to the tongue of the former jaw, said tongue and said projecting portion forming pinch handles, the jaws being also formed respectively with a coacting opening and prong for entering the opening, zubstantially as and for the purpose speci- In testimony whereof, I have hereunto signed my name at Syracuse, in the county of Onondaga, and State of New York, this llth day of March, 1919.

BOARDMAN E. TREIBER.
